在中国辐射防护研究院（ＣＩＲＰ）试验场用Ｃｏｚ－（ＣｏＣｔ２”６ＨｚＯ）、Ｓｒ’”〔Ｓｒ（ＮＯａ）２」作喷淋液进行了１４４０ｈ的淋滤试验，得到了Ｃｏ、Ｓｒ在包气带土壤中迁移的平均阻滞系数；重点采用水文地球化学理论对试验结果作了解释，指出Ｃｏ、Ｓｒ’”的迁移主要受溶度积规则控制，且与土壤和孔隙水中Ｃｏｌ含量有关。 A 1440h leaching test was conducted at the CIRP test site with Coz- (CoCt2 “6HzO) and Sr ’” [Sr (NOa) 2 " With the average retardation coefficient of migration in soil. The hydrogeochemistry theory is emphatically used to explain the test results. It is pointed out that the migration of Co, Sr ’’ ’is mainly controlled by the law of solubility product and is related to the content of Col in soil and pore water.
